Units becoming unavailble

[Pel1can111]

I am currently unsure if this is a problem with my setup or a bug in HA or this plugin but I set up an automation to alert me to any changes in the error code reported by the indoor units. I'm not sure if it started happening after the latest update with this plugin or the latest version of HA but I am randomly getting notifications due to the units becoming unavailable. Looking at the logs they seem to just briefly become unavailable then return to normal. This is something that would not be noticable if it were not for the notifications I had set up.

Please could other users just check their logbook and see if their units are doing the same so I know if this is a problem with HA or something with my units?

Thanks

I have 3 airco units (1x srk50zs-w and 2x srk25zs-w) for several years now and the connection has all that time been flippering always. See below the log I just pulled which is only 4 minutes (but this goes on 24/7).

When the airco's were installed I had a Netgear (WiFi) router + used only the smart-m air app and the flippering was already there. The past year I went from netgear to Unifi (with multiple Access points) and from the smart-m air app to home assistant with this great integration, but the flippering never changed (even though 2 airco's are right next to WiFi access points). So except from the WF-RAC module all other variables have changed.

I further have in total 47 devices connected to the access points (probably around 40 of which IoT goodies) and none of them show up as losing connection in the logs (thus have stable connections, even some of them being at the utter edge of the WiFi signal). Except, as you can see above, for the 3 airco's that are real log fillers disconnecting/connecting every minute or so all day long.

So, unless there is a setting for the Airco/WF-RAC I don't know about and is configured wrong... I have to come to the conclusion that it has nothing to do with the integration but, in fact, has to do with the WF-RAC module's themselves not really being stable in holding a WiFi connection.

I'd always thought this was something that I just had to live with as being an oddity of MHI. But if you are saying that it's not normal I'd like to hear that also off course (and take a deep dive in the settings of the 3 WF-RAC modules, although I believe there is not much to set up in them).

@Dream1975

you have some WiFi/network issues looking at that small output. Certainly concerning enough to investigate.

I just got around to look a little further in the fact my airco's (dis)connect every minute....

Airco wise there is just not that much that can be wrong as the settings are minimal. I logged into the accespoint and did a tail -f /var/log/messages (I just noticed all three airco's connect to the same AP even though for one of the airco's there is another one nearby).

It's all a bit jibberish for me, would someone mind to have a look if a point of interest rises out of this 4 minute log regarding the connection? Log airco.txt

Ps. Hope you don't mind asking a small beside question in the thread?

just had a Quick Look since this is not the place for this one

recommend limiting your dB-80+ is to high. No idea what the roaming threshold is on these units but I suspect your past it which would exasperate your issues.
